Gamezilla has produced a massive 10-page long NWN2 review, going through every aspect of the game and answering every question you may possibly have.

Donâ€™t make a mistake here. This game isnâ€™t what Iâ€™d call great. With a clumsy interface and some pretty serious performance issues, I think that NWN2 couldâ€™ve used a lot more polish. However, it is built perfectly for the hardcore DnD fan. It delivers a more accurate DnD experience than many other games Iâ€™ve seen, and if youâ€™re into that, youâ€™ll definitely find this game worth it.

I haven't played NWN2, so I have absolutely no idea whether this opinion is accurate or not.
